Nice project Rob, as always I will be avidly watching the progress of your latest phase of the 850's progress. I like the 2.4 850 block mods and look forward to seeing what she makes on the rollers when completed, keep up the good work mate.

They work well, Adam from Wales did it on his 854R. Iirc volvo have now ran out of some of the rear suspension mounting brackets, they are easy to remove from a donor. I think Shem got a couple of sets when he did his shell and didn't use them all.

The donor car had a vibration that came from the centre tunnel, on closer investigation it was found that the centre bearing was a little dry but the centre UJ was seized these causing the vibration. Got a new brg on order along with a complete UJ, all should be here for the weekend.

Got the internal reinforcing plate welded in for the torque tube fixing point. Also found £7.42 between the sound proofing and the floor plan under the drivers seat. Looks like it's been there a few years.

May be worth taking it apart and cleaning the crud out of it, mine had done 160k and had a very thick layer of sludge around the whole inside, took me ages to scrape it all out. Plus there is ports off the main reservoir that splash oil through to the outer bearing on the output shaft. Quite an odd design really.

The only issue is tightening the output shaft nut, it has to be done to a specific torque as there is a crush ring on the shaft.

I guess a P2 collar won't fit into the hole on a P1 angle gear? (thinking machine down a P1 collar to fit inside a machined P2 collar for the angle gear side). And I guess S60R angle gears aren't cheap?

Picked up a M66 diesel xc 70 gearbox during the week and thats when the fun started. After searching the good old internet I couldn't find nothing to comfirm whether the diesel collar was the same as the petrol collar. Well I can confirm that the diesel collar has 47 splines and the petrol collar has 45 splines. So I'm going to see if i can get a custom collar made with 47 splines at 1 end and 45 at the other end.
I can also confirm the S60R angle has a ratio of 2.56 - 1 and fits the M58 gearbox.

A P1 v70 awd angle gear compared with a P2 S60R angle gear.

So after the fun and games with angle collars I fabricated the new M66 gearbox mount.
